4D BIM for linear projects using Tilos 11 & Navisworks

Explore planning and scheduling of linear projects through a simplified viaduct and cut‑and‑cover tunnel modeled in Revit, using Navisworks for quantification and Timeliner, and Tilos for 4d scheduling.

Learn to use Tilos for 4D BIM of linear projects by scheduling with time and location, managing start dates and distances, and applying finish-to-start links in an integrated view.

Perform quantity take-off in Navisworks from Revit model using shared parameters and NWC export; build a tailored WBS to quantify abutments, piles, foundations, elevations, slabs, curbs, and asphalt for Tilos.

Export the plan view and section view from Revit to DWG files, export the lateral view as DWG, and import the longitudinal profile and plan into Trimble Tilos.

Export Revit views to a DWG file and import the bridge and tunnel profiles into Tilos, then set coordinates, distances, and timing to drive a 4D BIM workflow.

Learn to paste AutoCAD plans into tilos, insert distance scales, and align longitudinal profiles with master cells for precise timescale visualization.

Master the time distance diagram in tilos: add activities and summary tasks, link them with finish-to-start and lag, and explore the critical path method and total float.

Create and refine a WBS in Tilos by importing activities from Microsoft Project and Excel, mirror NavisWorks structures for bridges and tunnels, and generate a time distance schedule.

Import the WBS tree into Tilos, define tunnel segment start and end distances with 25 m lengths, and adjust slab, foundation, elevation, and asphalt coordinates before saving.

Create and customize Tilos activity templates, name sub templates (foundation, elevation, slab, abutment, asphalt), apply them to time distance diagrams, adjust durations, colors, and annotations for bridges and tunnels.

Create and interpret a time-distance diagram from the Gantt view to schedule a bridge project, adjusting task templates, links, and annotations, and calculating durations from quantities and rates.

Build a time-distance diagram in tilos to sequence piles, curbs, slabs, and asphalt, manage overlaps and machine moves, and apply geotechnical profiles to adjust productivity.

Calculate durations from work rate and quantity to link curbs and slabs in time distance diagram, detailing concrete volumes, steel rebars, and a 5-day lag with 28-day curing before excavation.

Detect clashes in the time-distance diagram with tilos 11 and optimize excavation, piles, curbs, and foundations by adjusting lags and links.

Coordinate excavation and foundation on two fronts with tilos, using left-to-right and right-to-left progress, finish-to-start links, and lags to optimize elevations in a linear project.

Export the Tilos schedule to CSV, import to Navisworks, and drag curbs, piles, slabs, foundation, elevation, and asphalt into the 3D model to create a 4D BIM tunnel simulation.

Link the time schedule to a bill of quantities with 4D BIM to automatically update quantities and adjust the project duration when pile lengths change.

This 4D BIM lecture demonstrates how changing the 3D model updates quantities and the time schedule automatically in Revit, Navisworks, and Tilos, enabling rescheduling and schedule optimization.
